2011-02-14x86: Fix mwait_usable section mismatchBorislav Petkov
We use it in non __cpuinit code now too so drop marker. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com> LKML-Reference: <20110211171754.GA21047@aftab> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2011-01-21x86, hotplug: Fix powersavings with offlined cores on AMDBorislav Petkov
ea53069231f9317062910d6e772cca4ce93de8c8 made a CPU use monitor/mwait when offline. This is not the optimal choice for AMD wrt to powersavings and we'd prefer our cores to halt (i.e. enter C1) instead. For this, the same selection whether to use monitor/mwait has to be used as when we select the idle routine for the machine. With this patch, offlining cores 1-5 on a X6 machine allows core0 to boost again.

2010-08-12x86, cleanup: Remove obsolete boot_cpu_id variableRobert Richter
boot_cpu_id is there for historical reasons and was renamed to boot_cpu_physical_apicid in patch: c70dcb7 x86: change boot_cpu_id to boot_cpu_physical_apicid However, there are some remaining occurrences of boot_cpu_id that are never touched in the kernel and thus its value is always 0. This patch removes boot_cpu_id completely. Signed-off-by: Robert Richter <robert.richter@amd.com> LKML-Reference: <1279731838-1522-8-git-send-email-robert.richter@amd.com> Signed-off-by: H.

2009-01-29x86: generalize boot_cpu_idIngo Molnar
x86/Voyager can boot on non-zero processors. While that can probably be fixed by properly remapping the physical CPU IDs, keep boot_cpu_id for now for easier transition - and expand it to all of x86. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-10-22x86: Fix ASM_X86__ header guardsH. Peter Anvin
Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
